||v| PRovi-:MENT IN I-IAY-PRESSES.`

Specification forming part of Letters Patent No. 3,56] dated April 25,I1844.

To a/ZZ whom it may concern.- i Be it known that I, CHARLES F. PAINE, ofWinslow, in the county of Kennebec, in the State of Maine, have inventeda new and useful Improvement in Hay-Presses and I do hereby declare thatthe following description and accompanying drawings, taken inconnection, constitute a full and exact specification of my invention.Figure l of the drawings above mentioned represents a side elevation ofmy improved press. Fig. 2 is a central, vertical, and longitudinalsection thereof. Fig. 3 is an end elevation of the same, and Fig. L is atop view thereof. j .i The body of the press consists of an uprightframe, A, formed of posts and cross-ties suitably tenoned and boltedtogether, and lined on the inside thereof with boards or planks in theusual manner. The upper part, B, of thev front and rear sides is made toturn down or outward upon hinges arranged in any suitable manner, whilethe top or bed plate, O, is also hinged or otherwise similarly connectedto the frame, so as to admit of its being turned upward into a verticalposition. When in a horizontal position it is confined therein or to theframe by means of pins or bolts, or in any other convenient and propermanner. The platen or follower D (see Fig. 2)is supported by two longvertical rods, E E, which are connected to the same by links F F, eachof which is jointed to one of the rods and to the platen in such mannerthat a depression of the rod will cause the lower end of it to moveoutward or away from the end of the platen. The upper endof each of therods E E is connected by a hinge-joint, G, to the top of an extended orlong lever, H, whose fulcrum is at its center, or thereabout, and upon abolt, I, passing through it and the top of two shorter levers, K K,arranged on each side of the long lever, as seen in Fig. 3. The feet orlower ends of the two short levers K K rest and turn upon abolt, L,passing throughthem, and three cheeks or pieces of hard wood, M M M,Figs. l, 2, 3, rmly bolted to the end of the frame A. The lower end ofone of the extended levers has a rope or chain, N', attached to it,which proceeds therefrom and winds around the barrel of a windlass, O,applied to the side of the press just below the cheeks M M. The lowerend of the opposite extended lever has a horizontal cross-bar, l?,bolted to it, the ends of said cross-bar extending each way from thelever a sufficient distance to admit of two ropes or chains, Q Q, beingattached to it and extended therefrom to the windlass-barrel. On windingup the windlass by any suitable lpowerl applied thereto the lower endsof the extended levers will be drawn toward the ends of the frame, whichoperation will cause the toggles to move inward and elevate the platenor follower toward the top or bed piece.

The rods E E may have a horizontal bar, E, extending from one to theother, as seen in Fig. l, in order to steady them at their upper ends. i

The planks S S, Fig. 2, composing the ends of the pressing-box, andwhich are disposed against the sides of the upright rodsE E, are connedat their lower ends t9 the frame of the box, their upper ends being leftfree, so as t0 easily spring outward. They (the said upper ends) restagainst turning lever bars or blocks T T T T, which are composed ofhorizontal pieces of timber having journals on their ends, as seen atFigs. 5, 6, the former figure being a top view of the lever-bar and thelatter an end view thereof. The said j ournals play in suitable bearingsformed lin the vposts of the frame A, and each of the inner sides of thelever-bars is rounded, 'as seenat b` in Figs. 5 and 6, and extendsbeyond the axis of the journals a greater distance than that between theaxis and the upper and lower surface of the bar T. A rod or iron bar, c,is inserted in each bar T, as seen in the drawings, the object of therod being to enable a person to turn the lever-bar on its journals. Whenthe rods of all the bars are turned into a vertical position, the sidesor planks S S may be pressed away from the bale of hay, or may be forcedoutward 5 but when the rods are turned down toward a horizontal positionthe rounded edges of the bars crowd the sides S S in wardly a shortdistance toward each other. By this arrangement it will be seen thatafter the pressure of the hay has been completed the ends of thepressing-box may be moved from close contact with the ends of the bale,so as to permit the latter to be easily with drawn from the press.v Aslight vertical dea pression of the rods E E will cause them also to bemoved away from close contact with the ha f.

Iaving thus described my invention I shall now proceed to state suchpart thereof as I claim, and for which I desire to secure LettersPatent, Viz:

Connecting the feet of the platen-rods E E with the platen or followerby means of links or other contrivances of similar character, the Objectof the said links being to lpermit the lower ends of the rods to bemoved laterally from the ends of the bale, as set forth.

In testimony that the foregoing is a correct description of myimprovements I have hereto I set my signature this 7th day of September,A. D. 1843.

CHARLES F. PAINE.
